Emerson is a global industrial automation company that makes and sells the hardware and software industrial manufacturers use to automate and optimize their operations. Emerson's products span the full automation technology stack: intelligent devices (control valves, pressure/safety valves, sensors, and instrumentation), control systems (DeltaV and Ovation distributed control systems), asset optimization software (AspenTech), and automated test and measurement equipment (formerly National Instruments). Key brands include Fisher, Rosemount, Micro Motion, ASCO, and Greenlee. Emerson sells primarily through a direct sales force to process, hybrid, and discrete manufacturers across chemicals, oil & gas, LNG, power, life sciences, food & beverage, semiconductor, and automotive end markets. Roughly 65% of sales come from MRO spending tied to Emerson's large installed base, with the remaining ~35% from capital projects. Emerson generates revenue through hardware sales, large integrated automation project contracts, and software subscriptions — AspenTech licenses are sold as multiyear term contracts tracked via Annual Contract Value (ACV). Emerson has spent 2021-2025 transforming its portfolio, divesting non-automation businesses and acquiring NI and full control of AspenTech to concentrate around industrial automation. Emerson's four priority growth verticals are power and grid, LNG, life sciences, and semiconductor. Longer term, Emerson is pursuing a "boundless automation" vision — a software-defined architecture integrating field devices, control systems, and optimization software into a unified platform.
